CAUTION
Do not wire vacant pins.
CAUTION
Apply 12V DC power for input signals on the pump side. Do
not apply this voltage on the equipment side.
The output signals are generated from an open collector
output. Apply a voltage not exceeding 50V DC on the
equipment side.
CAUTION
Wire all signals with the correct polarity
(SIGNAL/COMMON).
CAUTION
When output signals energize an inductive load, such as a
relay, insert a diode (100V. 1A class) to absorb the back
electromotive force from surge currents.
